The study will evaluate the various alternatives for a rail connection from the high-speed line to destinations in King of Prussia and Upper Merion Township in Montgomery County, SEPTA officials said in a prepared statement.

The line current provides service between SEPTA's 69th Street and Norristown Transportation Centers, serving the Main Line area in Delaware and Montgomery counties, and connecting to Center City Philadelphia. The extension would provide riders a direct route from 69th Street and Norristown to destinations in the King of Prussia and Valley Forge area.
